In this article,we will learn about different Date conversion from String to Date.


Sometimes project requirements demand capturing Date in string,and sometimes it's also required to convert from string to Date-Time.
For working with String to Date conversion,we have to convert string date to Date then apply some format to have a Date-time values.

There are lots of Date Format as Microsoft has provided us,we can give our own format.
DateTime.Parse supports many formats like dd/MM/yyyy, MMM-dd-yyyy, dd-MM-yyyy and many more formats.It is versatile and it can provoke a FormatException.

With Date object ToString,DateTime.Parse or DateTime.ParseExact method,we can pass above date formats to get the date we desired.

DateTime.Parse:- It is a static method that we can call without using a Date-Time instance. It returns a new Date-Time instance,which is represented as a Struct. If time is not provided, "12 AM" is used.

TryParse:-Whenever we have a string containing a date and time that may be invalid in formatting or that never occurred,we can use the DateTime.TryParse static method.It is in the System namespace.

It converts the string to a Date-Time instance without raising an exception on errors.


Different Date conversion from String to Date.

Using the code

We will understand with an example:-

In the code-behind,we will create one method named convert_string_to_date() and in the Page Load event,we will call that method as shown below:-

 protected void Page_Load(object sender, EventArgs e)
if (!IsPostBack)

/// <summary>
/// converts following string date into date pattern
/// </summary>
private void convert_string_to_date()
string ds1 = "Sep 2013";
string ds2 = "Monday 2 September 2013 14:15:33";
string ds3 = "2,9,13";
string ds4 = "2/9/2013 14:15:33";
string ds5 = "2:15 PM";

// 1st September 2013 00:00:00
DateTime dt1 = DateTime.Parse(ds1);

// 2nd September 2013 14:15:33
DateTime dt2 = DateTime.Parse(ds2);

// 2nd September 2013 00:00:00
DateTime dt3 = DateTime.Parse(ds3);

// 2nd September 2013 14:15:33
DateTime dt4 = DateTime.Parse(ds4);

// Current Date 14:15:00
DateTime dt5 = DateTime.Parse(ds5);

// Display the converted DateTime objects.
Response.Write(string.Format("String: {0} DateTime: {1}", ds1, dt1));

Response.Write(string.Format("String: {0} DateTime: {1}", ds2, dt2));

Response.Write(string.Format("String: {0} DateTime: {1}", ds3, dt3));

Response.Write(string.Format("String: {0} DateTime: {1}", ds4, dt4));

Response.Write(string.Format("String: {0} DateTime: {1}", ds5, dt5));

// Parse only strings containing LongTimePattern.
DateTime dt6 = DateTime.ParseExact("2:13:30 PM", "h:mm:ss tt", null);

// Parse only strings containing RFC1123Pattern.
DateTime dt7 = DateTime.ParseExact(
"Mon, 02 Sep 2013 14:13:30 GMT", "ddd, dd MMM yyyy HH':'mm':'ss 'GMT'",

// Parse only strings containing MonthDayPattern.
DateTime dt8 = DateTime.ParseExact("December 05", "MMMM dd", null);

DateTime dt9 = DateTime.ParseExact("December 05", "MMMM dd", System.Globalization.CultureInfo.InvariantCulture);

var dt10 = DateTime.ParseExact("24/12/2013", "dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture);

Response.Write("<b>Below Output Displays the Converted DateTime objects</b>");

// Display the converted DateTime objects.
Response.Write("Date Conversion: " + dt6);
Response.Write("Date Conversion: " + dt7);
Response.Write("Date Conversion: " + dt8);
Response.Write("Date Conversion: " + dt9);
Response.Write("Date Conversion: " + dt10);
catch (Exception ex)
throw ex;
